RAIL- CHAIR AND RAIL-FASTENIN Specification of Letters Patent.

Patented J an. 26, 19315..

Application filed August 22, 1914. Serial No. 858,042.

To all whom it may concern:

Be it known that 1-, AUGUST G. LIEBMANN, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Rail-Chairs and Rail-Fastenings, of which the following is a specification.

This invention relates to track appliance, and particularly to chairs for supporting rails.

The primary object of the invention is to provide a chair which will not only support the rail against thrusts, but which will hold the rail securely to treated ties during track laying without damage to said ties and without re-spiking.

A further object of the invention is to provide means whereby the rail and chair may be held temporarily engaged with a tie, said means, however, being readily disengaged from the tie to permit the chair to be elevated or laterally shifted with the rail.

A further object of the invention is to provide a rail fastening which performs the dual function of a rail bracing and tie engaging member, and in this connection to provide a base plate with which the tie and rail engaging members will co-act so as to rigidly engage the rail on each side thereof and hold it in proper position.

A further object of the invention is to provide means for temporarily fastening the rail to a tie which will permit the resurfacing of subgrades in the introduction of ballast in new track.

A still further object of the invention is to provide a rail fastening of the character described so constructed that it may serve as a temporary means for holding bed-plates to ties during track laying with chairs.

Other objects will appear in the course of the following description.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a perspective view of one end of a tie, a rail thereon, and the improved chair and fastening mechanism; Fig. 2 is an elevation of a portion of the tie and the fastening mechanism, the rail being in section; and Fig. 3 is an end elevation of the fastening and tie.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

Referring to these figures, A designates a tie which may be of any ordinary form, and which is illustrated as a wood tie.

B designates a rail which may be of any standard cross section.

Disposed upon the tie is a bed plate 2 which has the form of a channel beam, this base plate being formed with an upwardly extending flange or abutment 3 at each end, the inner faces of these flanges or abutments being inwardly beveled, as at 4. This bed plate has a width between the flanges or abutments 3 greater than that of the rail.

Disposed between the abutments or flanges 3 and the base of the rail are rail clamping members which also constitute rail braces. There are two of these members on each side of the rail. Each member comprises a web 5 having a height at its inner end preferably equal to the distance between the base flange of the rail and the head thereof, as shown in Fig. 2. The upper edge of this web 5 extends downwardly and outwardly. The lower edge extends horizontally a dis tance equal to the width of the base flange of the rail and then the material of which the rail brace is formed is bent at right angles, as at 6, and extended horizontally for a distance, and then bent downwardly, as at 7, the inner face of this downwardly bent portion being formed with horizontally disposed teeth 8 constituting a gripping surface. The width of the portion 6 of each rail brace is equal to the distance between the edge of the base flange of the rail and the lower margin of the inner face of the abutment 3.

The outer edge face 9 of the portion 5 is downwardly and inwardly beveled, the inclination of this edge face being approximately the same as the inclination of the inner face of the corresponding abutment 3. As before stated, there are two of these rail engaging members on each side of the rail, said members having portions 6 extending in opposite directions so that the tie is embraced between the downwardly extending portions 7. The rail clamping members or braces 5 are adapted to be drawn together by means of a bolt 10 which passes through the rail braces, said bolt being provided with a washer 11 and with a nut 12.

are then drawn together by means .of the.

bolts 10 and the teeth 8 forced into the tie. Inasmuch as the teeth 8 bite into the tie, the

bed plate 2 will be held firmly down upon the tie and the rail B will be held firmly upon the bed plate. It will be seen that no accidental displacement of the rail can occur for the reason that the outer. edge of each rail brace bears againstthe corresponding abutment 3. When the rail braces are clampedby the bolts 10 and the teeth 8 are forced firmly into the tie, it is impossible to shift the rail braces upwardly or laterally; The bolt receiving holes are preferably of sufiicient diameter to permit the bolts 10 to bereadily driven out when desired. It is obvious, however, that, if it be desired to raise the rail, a shim may be inserted between the rail and the bed plate and the rail braces again clamped to the tie.

While, of course, this form of fastening may be used for permanently connecting the rail to the tie, where desirable or necessary, it is obvious that the principal use of the invention'will be in temporarily fastening the rail to the tie to provide for an adjustment of the rail while the sub-structure and ballast are in a disturbed condition in construction periods.

It will be obvious that the invention may be very cheaply made; that the parts interlock with each other; that thebase plate cannot shift, and that the rail cannot shift with relation to the base plate. The abutments of the bed plate perform the dual function of holding the rail to gage in the different positions of said rail, and as a means for supporting the railbraces in a truss-like manner, thus preventing buckling of the bed plate downwardly at its center and curling upwardly at its edges and permitting the employment of a bed plate of ordinary thickness. It will further be plain that this form of rail bracing, fastening and chair conforms to the requirements of the ofiicial report of the Block Signal and Train Control Board of the Interstate Commerce Commission, in that it'provides means for supporting the rail against tipping thrust, aswell as supporting the rail against horizontal and vertical thrusts, and that it provides for a vertical adjustment of the rail by means of shims. It will further be seen that it will be relatively easy to release these fastenings and insert a shim beneath the rail and then re-apply the fastenings so that contact with.

such re-adjustment does not require the services of a section gang with special tools.

Having thus described the invention, what is claimed as new is 1. A. rail fastening comprising a bedthen downwardly bent, the downwardly bent portions being provided with gripping faces, and means for drawing the members of each pair toward eachuother whereby to forceth'e gripping faces into atie and holding thebed-plate-against displacement.
